"CHURN.

srEcirIoA'r'IoN forming part of Letters Patent No. 700,385, dated May 20, 1902.

Application filed July 12, 1901. Serial No. 68,054. (No mtdelz) To ct ZZ whom. it may con/067%.- I

Be it known that I, MICHAEL M. SWEETMAN, a citizen of the United States,residing at Kansas City, inthe county of Jackson and State.

the receptacle and the. agitator, beater, 01-1 whip being shown in I section; and Fig.2, an end View.

The object of the invention is. to produce a simpleand eifective churn with whicha, small quantity of butter may be readily and The churn inthe embodi' ment illustrated is a portable one, though quickly made.

certain of its features may be employed-in larger churns, if sodesired.

. shown.

Referring to the drawings, A designates a suitable upright or standard, through the .up--- per end of whichextends an axle or stud'carrying a relatively large driving-wheel'fltherim of which is grooved to receive an endless bandor belt 0. The lower endof the stand; ard is provided with the usual clamp for securing the deviceftojthe edge'of a table or thellike An arm D extends out laterally from the standard A, the end of the arm be-' ing' bifurcated, as shown, formingtwo members E E. A pulley F is disposed on a horizontal pivot at a point on the arm D adjacent to its end members, the bottomof said pulley being injalinement with the openingintermediate said horizontal members or arms E. A spindle G is journaled in the members E, and a pulley H is rigidly affixed thereto intermediate said members.

The whip or beater I is made in'the shape vof an inverted cup or is bell-shaped, beingopenat the bottom and wholly closed at the top but for a series of openings J, formed therein near thenpper end. The openings by preference are inclineddownwardly, as A collar K is secured to the top of the whip, and a pieceof flexible shafting L forms the connection intermediate said collar and the spindle G. I r

Belt C, as shown, passes about the large I driving-wheel B and the pulleys F and H, the difference in proportion'between the driving and the driven members being such that parted to the whip,.and air is drawn down through the openings J and forced through I the cream within the whip. and up through the mass outside ofthe same.

out of .the lower portion thereof, and as a consequence draws the air in. through the openings J.

rial. This erraticimovement in conjunction with the air which is drawn in and forcedthrough thematerial effectually and rapidly separates the fat particles, producing butter in a .very short space of time.

Having thus described myinvention, what I claim is-- 1. In a churn,the combination ofabellshaped whip opengat its lower end, and provided with a relatively small opening in itsupper face above theline of immersion; and

a flexible shaft connected to the upper end .of the whip and forming-itssole means of support; and means for rotating said shaft.

In a churn, the combination of a bell form'edin its upper end a flexibleshaft'com nectedto the upper end of the whip and forming its sole means of support; and means con The rapid ro o w 1 tation of the whip tends to force the cream The flexible shaft also causes the whip Y to move aroundin the vessel in a somewhat erratic path or course, and thereby stirs up or agitates the entire mass of mate- I shaped'whip, open at its lower end and having'a series of downwardly-inclined openings nected to said shaft for imparting'rotary motion thereto.

3. In-a churn, the combinationofa bellshaped whip, open at its lower end, and hav-- ing a series of downwardlyvinclined openings in its upper end; a fiexible'shaft connected to the upper, end of the whip and forming its sole means of support; a spindle'connected to said shaft, said spindle being mountedin fixed bearings; a pulley carried by said spin dle; andmeans for imparting motion thereto. 4. In a churn, the combination of a receptacle; a whip having imperforate side Walls mounted therein; means for imparting rotary motion to said Whip and causing it to move about in the receptacle in an irregular path; and means for permitting air to pass into the interior of the whip and out through the bottom of the same.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
